LUBBICANT COMPRESSOR.

'Application tiled June 6,

My invention relates to improvements in vlubricant compressors and is particularly concerned with the provision of a novel type ol vcompressor to be used in those lubricating systems which comprise a plurality of` fittings to be secured to th bearings to be lubricated and a compressor having a discharge conduit, the tree end of which is First; to provide a compressor of the character described, the discharge conduit or which is ytormedvogt rigid pipe. i

Second; to provide e. compressor, the discharge conduit of which is formed of e plu-` I'relity ot sections which are so connected as titl to permit the coupling at the tree end of the discharge conduit to be positioned in practically any desired position so as to facilitate the connection ot they coupling with httings in more or less inaccessible positions.

rllhirdrto provide a compressor kcomprising a discharge conduit, the treel end of, which is provided with a coupling, the discharge conduit being rigid and the coupling being or such character as to ermit it tobe attached to a fitting without eing directly manipulateda Fourth; to provide a compressor of the character described in which the lportions of the discharg conduit ere connected by joints which are a` apted to withstand high pressures without leakingi but which cen be economically manufactured.

@ther objects will appear Vas this description progresses, reference being had to accompenying drawin s, 1n which ligure l is ve view s owing my improvedl compressor in side elevation in connection with a bearing 1which is shown in cross section, the hearing being provided with a fitting adapted to co-eet with the coupling of my compressor; y

central longitudinal sectiomshowing certain i details of construction of the discharge coni duit and 'coupling of my compressor.

Referring Fto the drawings, my improved compressor comprises a barrel 10 which may be of Aany desired type, but' which is here shown as having a detachable cap 11 `in whichpis threaded the rod 12, the innerend of which is provided with a suitable plunger or piston (not shown) and the outer end of which is provided with a handle 13 by means of which the rod 12 can be rotated' to reciprocate the plunver in the barrel'lO. The inner end of the discharge conduit'li,

which is termed ot rigid pipe ot any suitable materiel., is threaded into one end of the nlpple'l, the opposite end of the nipple being provided with a tubular extension 16' of reduced diameter. A gasket 17 is in, serted between the inner end of the conduit 14 and the nipple 1-5 to provide a Huid tight connection. `A sleeve 18 is rotatably mounted upon the tubular extension 16 and held in position by 4means ot a gasket 4'19 and washer 2O which are threaded onto the end of the tubular extension 16 and held in place over, as shown at .21. A 'coupling 22 is threaded into the screw threaded extension 23' of the sleeve 18 and its-opposite end is by swaging the end of the tubular extension connected'with e. short section 2t ot piper' y y the inner end of which is threaded into the discharge outlet 25ct the compressor barrel. "By means ot the construction described above the discharge conduit lll is swiveled y 'to the barrel 10 of the compressorso that it can rotate about its own axis. v

The outer or free end et the discharge conduit is threaded into one end or an elbow 26, The opposite end ot the elbow 2t is in the form et e tubular extension 2'? upon which is rotatably mounted e sleeve 28 having a threaded extension 29 which screws into the end ot asecond elbow 430. .A gasket B1 and a washer 32, secured to the outer end ot the tubuler extension 27, hold the sleeve 28 in position in the same manner in which the sleeve 23 is held by the gasket 19 and ring 20.

"" The other'end ofthe elbow @-10 .is in the term of atubular extension 33 upon which is rotatably mounted a sleeve 34 theft is held lill@ that r each comprises a female portion openin in ition by means of a gasket 35 and was er 36. It will be seen from an inspection of Figure 5 that the two elbows 26 and 30 are identical in construction, and that ln one direction and a male portion exten ing at right angles thereto for connection with the next element in the series.

A coupling 37 is threaded upon the screw thread extension 38 of the sleeve 34 and its outerend 39 is threaded into one side of the body member 40 of the coupling which I have illustrated as forming a part of my invention. This side of the body member 40l a is provided with an o ening 4l which registers With the bore 42 in the end of the couplin 37 to establish communication between the ischarge conduit and the bore 43 which extends through the body member 40.

The body member 40 is surrounded by a strap 44, the ends of which are secured beneath the flange 45 of the plug 46 which is threaded into one end. of the bore 43, as shown in Figure 5. The .opposite end of the bore 43 is provided with an inwardl extending flange 47 which forms a seat or a aug leather 48. A. compression spring inserte between the plug 46 and a washer 49 at the bottom of the cup leather 48 tends to hold the cup leather with its outer side projecting sli htly beyond the adjacent side 50 of the bo y member. The sides 44 and 44 of the strap 44 are longer than the adjacent sides of the body member 40, so that the side 44 is held in s aced relationtto the adjacent side of the ody member to provide a space for receivin the head 51 of the fitting or coupling 52 w ichl is secured to a bearing to be lubricated The side 44 of the stra .is provided with a notch 53 which exten s inwardly from on'e side thereof for receiving the neck54 of the ttin 52.

The details of construction of t e couplin described above are illustrated and describe in the copending application of Ernest W. Davis, Serial No. 444,932, filed February 14,

. 1921, and form'no part of my presentinvention except as they co-act with the other details of construction of my present invention. From the above description it will be seen that the rigid conduit 14 can be rotated upon its axis to position the elbow 26 in any desired position in its plane of rotation and t e elbow 30 can be rotated `upon the tubular extension 27 of the. elbow 26 to position its tubular extension 33 in any position in its plane of rotation and that, finally, the coupling can in a similar manner be ro'- tated upon the tubular extension 33, so that it is possible to position the couplin in any one of an innumerablev number of different positions and thus make it possible to properly position the cou ling to be secured to fitigs 52 whatever t eir position may be.

1 enever the coupling is so positioned the coupling. If the joints ofthe di that the connection with thel fitting can be made by a movement in either direction parallel with the discharge conduit 14, the connection can -be established without touching the coupling and b merely using the gun barrel 10 and disc arge conduit 14 as a handle to properly position and mani ulate rent swivel connections are made comparatively tight, then the cou ling can be connected with the fittings without directly manipulating it, irrespective of the position of the coupling, because it requires practically no force to engage the coupling with the fitting. When the compressor is then actuated to exert pressure u on the lubricant, the cup leather 48 is held against the adjacent end of the fitting by the pressure of the lubricant and thus locks the cou lin to the fitting until the pressure on tliie lubricant is released. i
